Ok well, there is NO way mq2 has anything to do with your boot times.
Let me say this:
EQ writes the full dump to C:\Crash and to your local temp folder for wws_X, that's given. If you can manage, don't load MQ2, and figure out how to make EQ crash, and you'll see it does that.
MQ2
used to bypass that crash report. Now, it allows it, but moves it out of the way, so it doesn't get sent to SOE.
Those dump settings are controlled by EQ, and by Windows. The loader I put in a method thanks to some particular whiny beotching a method to keep them cut down (what I put in my previous post in this thread). That's not me (or loader/MQ2) doing anything special, what I did was put in a folder watch, and if there are more than X (what you configured) dumps, it only keeps those X files, and deletes the others.
Again, that's not a matter of not creating them from EQ - that's just using the loader to clean them up.
If you want to specifically test and set your own settings for how windows/eq handles a user mode dump, then refer to this MSDN article by Microsoft:
Collecting User-Mode Dumps
